Meeting the many needs of data centre interconnect

High capacity. Density. Power efficiency. Client-side optical interface choices. Coherent transmission. Direct detection. Open line system. Just some of the requirements vendors must offer to compete in the data centre interconnect market.

“A key lesson learned from all our interactions over the years is that there is no one-size-fits-all solution,” says Jörg-Peter Elbers, senior vice president of advanced technology, standards and IPR at ADVA Optical Networking. “What is important is that you have a portfolio to give customers what they need.”

NextIO simplifies top of rack switching with I/O virtualisation

NextIO has developed virtualised input/output (I/O) equipment that simplifies switch design in the data centre.

"Our box takes a single virtual NIC, virtualises that and shares that out with all the servers in a rack"

John Fruehe, NextIO 

The platform, known as vNET, replaces both Fibre Channel and Ethernet top-of-rack switches in the data centre and is suited for use with small one rack unit (1RU) servers. The platform uses PCI Express (PCIe) to implement I/O virtualisation.

Differentiation in a market that demands sameness

Transceiver feature: Part 2

At first sight, optical transceiver vendors have little scope for product differentiation. Modules are defined through a multi-source agreement (MSA) and used to transport specified protocols over predefined distances.
